Explanation:
Dynamic Host Configuration Protocol (DHCP) is an enhancement over Bootstrap Protocol (BOOTP). DHCP is
used to automate the distribution of IP address to clients from a central server. BOOTP protocol was also used
distribute IP addresses, but was inflexible when changes were made in the network. DHCP offers the following
three advantages, which also addressed the inflexibility of the BOOTP protocol:
Automatic allocation of permanent IP addresses
Automatic allocation of time bound (leased) IP addresses
Provision of assigning static IP address or defining a pool of reserved IP address
The following steps are used to allocate IP address dynamically using a Cisco IOS DHCP server:
1. The client device broadcasts a DHCPDISCOVER broadcast message to locate a Cisco IOS DHCP server.
2. The Cisco IOS DHCP server replies with a DHCPOFFER unicast message containing configuration
parameters such as an IP address, a MAC address, a domain name, and a lease for the IP address for the
client device.
3. The client sends back a DHCPREQUEST broadcast, which is a formal request for the offered IP address to
the Cisco IOS DHCP server.
4. The Cisco IOS DHCP server replies to client device with DHCPACK unicast message acknowledging the
allocation of the IP address to this client device.
While DHCP is very useful in reducing the administrative burden of issuing IP configurations in a large network,
Cisco best practices call for using static IP addressing in a small (6 or fewer hosts) network.
